    Author: Slavicek R, Sato S.
    Journal: Wien Med Wochenschr; 2004 Dec; 154(23-24):584-9. PubMed ID: 15675433.
    Abstract:
    Bruxism is generally defined as a parafunctional clenching and grinding action between the upper and lower teeth. During this activity, extremely strong forces can be applied for time periods exceeding those of functional mastication. These biomechanical loads create many dental problems, such as abfractions, hypersensitivity, periodontal distraction, and temporo-mandibular dysfunction. Researchers studying Bruxism have long discussed psychic stress and emotional tension. It has also been indicated that an aggressive biting is associated with a significant attenuation of the stress-induced increase of nor-adrenalin turnover in the brain, of the striatal DOPAC contents and with the prevention of stomach ulcer formation in experimental animals. The concept of stress management based on the psychological background of Bruxism and the benefits attributable to masticatory muscle activity in attenuating stress-related symptoms such as stomach ulcer. The clenching and bruxing function of the masticatory organ is an emergency exit during periods of psychic overloading. Therefore, occlusion of the masticatory organ contributes significantly to an individual's ability to manage stress. Bruxism in proper dentition can be recognized as a valid system prophylaxis for all stress related diseases.
